    2015 GMC Sierra 1500 2WD 4.3L 3.23 gears
  1. I have a 2015 GMC Sierra Single Cab 4.3L V6. Pulled into the parking lot at work this morning with no issues. Went to back into a parking spot and when I shifted into reverse, EVERYTHING in the cab shut off for about 3 seconds. When it came back on I had an airbag alarm and a stabilitrak alarm. I backed into the spot without issue. As far as I could tell the drive-train was fine. I have the convenience package which is basically the backup camera, Bluetooth, and On-Star. Anyone else come across this issue or anything similar?
  2. If you use a speaker with high dB sensitivity, they will perform "ok" with the stock head units power output. Will definitely be an improvement over stock, but certainly doesn't beat speakers powered by an amp.
  3. I have a Diablo tuned 4.3 and pull a camper with no issues. Does not lack in power. The transmission and torque converter are shameful though.
  4. Yea. I just noticed there was a design change and it seems to be better built.
  5. Also, the design of the pedal has changed to make it stiffer if anyone is interested in "upgrading." Old: https://www.rockauto.com/en/moreinfo.php?pk=7985184&cc=3307664&jsn=426 New: https://www.rockauto.com/en/moreinfo.php?pk=8931240&cc=3307664&jsn=427
  6. Water/Methanol Injection?

    https://www.snowperformance.net/Stage-2-MAF-MAP-Water-Methanol-injection-system-p/sno-212.htm This is the kit I was looking at. If anyone has another reputable company that deals with water/methanol injection, let me know. I just like the ease of install and support these guys are said to offer.
  7. Water/Methanol Injection?

    I like the Stage 2 Kit from Snow Performance. Uses the readings from your MAF sensor to adjust the injection. Definitely requires tuning though. I bet someone has a catch can thread also since carbon build-up is a known issue. If anyone has a link to such a thread they should post it
  8. Water/Methanol Injection?

    I understand. The performance increase would be nice as well. If I wasn't tuning and modifying the truck, I'd only worry about the catch can. Hoping someone post an example so I can see what kind of gains they received.
  9. Water/Methanol Injection?

    True. I have the truck tuned already. Mostly to disable AFM and Torque Management. I might just do the catch can first and scope the intake valves to see the difference. I'd still like to see an example of water methanol though. Looking at a stage 2 kit from snow performance. Pretty easy install. Easy to adjust.
  10. Water/Methanol Injection?

    Sea Foam sales an aerosol can with a long bent straw. Goes in at the throttle body. Allows you to have everything tightened up. http://www.acehardware.com/product/index.jsp?productId=20790476&msclkid=54f1fe71a1fb1089e34ea568e3a9e1d1&cid=CAPLA:B:Shopping_-_Catch_All&utm_term=4582283428594338&bingpla=bingpla_15718044&utm_campaign=Shopping - Catch All&utm_source=bing&utm_medium=cpc&k_clickid=a4ab8056-7d9f-42e0-b6d6-432a0efe84ee&utm_content=Catch All
  11. Water/Methanol Injection?

    I thought about doing that. Or both. Catch can would be about $200 cheaper.
  12. Has anyone installed a water/methanol inject kit on any of the small blocks (2014-2018)? I personally have the LV3 4.3L V6. Looking to eliminate the carbon build up, caused by direct injection, on the intake valves. Right now I'm trusting that Sea Foam is doing the job every 30k miles. EDIT* I'm also interested in the increased performance after tuning. I am aware that a catch can would eliminate the majority of carbon build up on the valves.
  13. Shake or Vibration Issues

    I'd recommend KYB MonoMax shocks for the rear. Bilsteins for the front. Especially if you're not planning to haul anything. IMO the KYBs are better engineered for the rear of a pick up. Loaded or unloaded.
